Electron diffraction studies of laser‐pumped molecules. IV. SF6, experiment and theory
(The American Institute of Physics, 1984-07-01)
A model of absorption of infrared radiation by supersonic jets proposed in paper III was tested experimentally. New nozzle designs permitted pumping the ν3 mode of SF6 at power densities in excess of 104 W/cm2. Vibrational ...
Monte Carlo methods for radiation transport analysis on vector computers
(Elsevier, 1984)
The development of advanced computers with special capabilities for vectorized or parallel calculations demands the development of new calculational methods. The very nature of the Monte Carlo process precludes direct ...
Optical measurement of profile and contact angle of liquids on transparent substrates
(Springer-Verlag, 1984-09)
Strong weak interactions
(Elsevier, 1984-12-24)
We study the intriguing and attractive possibility that the standard model Higgs particle is very heavy or does not exist at all and that, as a consequence, a spectrum of vector boson bound states emerges.
Growth of amorphous Ti2O3 layers by laser‐induced oxidation
(The American Institute of Physics, 1984-10-15)
Amorphous Ti2O3 films with thicknesses ≳103 Å have been obtained by cw laser irradiation of Ti50Zr10Be40 exposed to low oxygen pressures. In contrast, thermal oxidation of (nonirradiated) samples reveals scales composed ...
The [beta] function of the two-dimensional non-linear [sigma] model
(Elsevier, 1984-11-22)
Improved MCRG methods are used to determine the [beta] function of the two-dimensional O(3) standard action [sigma] model. We argue that the previously observed anomalous behavior of the mass gap can be understood as a ...
Radiation-affected laminar flame quenching
(Elsevier, 1984-08)
Under the influence of radiation, the increase in Peclet number characterizing the flame quench distance [Delta], , and the decrease in flame temperature are shown in terms of an original radiation number , where [varrho] ...
Exciton transport in disordered crystals: velocity correlation functions
(Elsevier, 1984-09-15)
The two-particle coherent-potential approximation is used to calculate Frenkel-exciton group-velocity correlation functions for substitutionally disordered crystals. Most of the results can be described by a relaxation-time ...
Fractal-like energy transport and fusion in a naphthalene-doped polymeric glass
(Elsevier, 1984-12)
Singlet energy transport in naphthalene-doped poly (methylmethacrylate) (PMMA) samples has been found, by doping with anthracene, to follow Stern-Volmer kinetics with a transfer rate constant ca. 2x109. Delayed fluorescence ...
Electron diffraction studies of supersonic jets. VII. Liquid and plastic crystalline carbon tetrachloride
(The American Institute of Physics, 1984-02-15)
Carbon tetrachloride at 3–11 mol % in neon carrier produces clusters of CCl4 molecules in flow through a Laval nozzle. Electron diffraction patterns of the clusters formed at a total pressure below 2.5 bar are intermediate ...
